The androgen receptor gene is more than 90 kb long and codes for a protein that has 3 major functional domains: the N-terminal domain, DNA-binding domain, and androgen-binding domain. The protein functions as a steroid-hormone activated transcription factor. Upon binding the hormone ligand, the receptor dissociates from accessory proteins, translocates into the nucleus, dimerizes, and then stimulates transcription of androgen responsive genes. This gene contains 2 polymorphic trinucleotide repeat segments that encode polyglutamine and polyglycine tracts in the N-terminal transactivation domain of its protein. Expansion of the polyglutamine tract causes spinal bulbar muscular atrophy (Kennedy disease). Mutations in this gene are also associated with complete androgen insensitivity (CAIS). Two alternatively spliced variants encoding distinct isoforms have been described. [provided by RefSeq, Jul 2008]

Technology:

DiscoveRx Protein Interaction Assays are cell-based assays designed to measure protein interaction in engineered cell lines using our proprietary EFC technology. The interaction can be triggered by protein activation/inactivation and is the basis of several DiscoveRx cell based assays including the Arrestin and the Kinase assays. Learn more about our Cell Based Protein Interaction Assays.

DiscoveRx Protein Translocation Assays are cell-based assays designed to measure protein translocation in engineered cell lines using our proprietary EFC technology. The translocation can occur to either the endosome, membrane, cytosol or nucleus and can be triggered by protein activation/inactivation. This forms the basis of several DiscoveRx cell based assays including the GPCR Internalization and the NHR Translocation assays. Learn more about our Cell Based Translocation Assays.
